4 Claims.

This invention relates to wall construction in which sheathing isemployed, and is particularly adapted, as will appear, to exteriorsheathing applied in the form of panel members.

The invention contemplates a panel member unit of sheet metal having ahigh glossy finish as of vitreous enamel. An object of the invention isto provide that the reecting effect of such lustrous nish shall bediminished as to the,

observer, so that the glistening appearance' of the wall will bediminished. As will appear, this is accomplished by deformations in theexposed surface.

The invention also contemplates a manner of mounting the panel unitsgenerally similar to the arrangement disclosedin the copendingapplication, Serial No. 655,224 filed February 4, 1933 jointly by MunroW. Copper, Jr., and me, andmy copending applications, Serial No. 673,190filed May 27, 1933, and Serial No. '711,176 filed February 14, 1934. Inthese said applications is disclosed a system of parallel runners ofchannel form, between which sheathing panel members are mounted, byengagement of lips upon the panel members, projecting into the runnerchannels. The nature of interengagement of the mounting parts tends tosubject the panel parts between the runners to slight bending and/ortensile stresses. A further object of the invention is to provide thatthe face parts of the panel members shall not be deformed by suchstresses; and as will appear the invention utilizes for the purpose, thesame deformations by which the glistening appearance is controlled, asalready described above.

Said copendng applications and this invention as well, contemplate theemployment of non-metallic heat and sound insulating backing means forthe face parts of the panel units. A further object of this invention isto provide improved means for securing such backing, as will appear.

The exact nature of this invention together with further objects andadvantages thereof will be apparent from the following description takenin connection with the accompanying drawing, in which Fig. 1 is aperspective view partly in section and. partly broken away and takengenerally as from the outside, in elevation, showing the elementsessential to an embodiment of the invention; and Fig. 2 is an enlargeddetail in horizontal section at a vertical joint between panel units, asindicated by the line 2-2 in Fig. 1.

With reference now to the drawing, A, A represent generally a pair ofsheathing panel units (Cl. 18S- 85) to be mounted beside each other uponthe wall 2 inturned to enter the cavities l of the correi spending pairof runners B, to engage the near sides of the latter with resilientcharacteristics. Obviously by this arrangement a panel unit is mountedfor support upon a pair of runner members by simply pushing thesheathing panel, suitably positioned. A backing 3 of non-metallicmaterial having heat and sound insulating properties, is provided forthe face part of each sheathing panel unit. The runner members B areprovided with the shoulders indicated, in which the backing panels 3 arepositioned, and by which a stop is provided for the inward mountingmovement of the panel units.

As indicated the panel members themselves are of `sheet metal. They arepreferably faced with vitreous enamel or the like, baked on, andproviding a surface of extremely high luster-too high to be serviceableas an exterior finish. That the effect of this lustrous surface bediminished, the face parts of the panels are provided as indicated inFigs. 1 and 2, with deformations running between their lip parts 2. Suchdeformations may be of 4such depth to produce shadows, but at any ratethey break up the plain reiecting surface that would otherwise resultfrom the high luster finish. The appearance of the surface from anydistance is thus softened and made more pleasing, with just enoughluster remaining for the purpose. A

Such deformations produce another effect as well. Running vertically,they strengthen the face parts of the panel units between the runners B.Thus, regardless of stresses set up by the mounting forces upon the lips2, the faces of the sheathing panels are maintained in the commongeneral plane.

At each vertical joint between adjacent sheathing panel units,astretcher is provided, slidably to extend between the correspondingpair of runners B. Each stretcher is provided with a Cil tongue at eachend extending into a groove on the runner members as at 4. Eachstretcher is generally of channel form between its runners, as indicatedparticularly in Fig. 2, with a pair of side members 5 forming a channelcavity 6 therebetween. The side edges of the panel units are providedwith lips l, the parts being so proportioned and arranged that the lips'I enter their cavities 6 when panel units and stretchers are mounted onthe runners. Preferably also the arrangement is such that the partsmaintain their spaced relation as in Fig. 2. The stretchers are alsoprovided with laterally extending flanges 8 adapted to providedshoulders for positioning the side edges of the panel backing means 3,along the vertical joints in a. manner generally similar to thedescribed provision at the horizontal joints.

The manner of assembly will be apparent, assuming the runners B mountedupon the frame or body part of a wall. The stretchers are mountedbetween their runners and suitably adjusted therealong, and thesheathing panel units are then applied to the assembly simply bypressing them to engage their lips2 in the channels of the runners; thestretchers being of course suitably positioned along the runners thatone underlies the vertical joint between each adjacent pair of sheathingpanels between a common pair of runners. It will be appreciated thatsheathing panel units will be applied to extend both above and beloweach runner although such additional panel units do not appear inFig. 1. The backing members 3 are applied to the assembly eachimmediately before the application of its sheathing panel thereover, andthe stretchers are conveniently positioned each against a backing memberjust laid and before application of the sheathing panel.

After completion of the described assembly, an exterior surface will beformed, of a plurality of panel unit faces in rectangular pattern, withchannel cavities therebetween, provided along the horizontal joints bythe runners B, and along the vertical joints by the stretchers. Plasticsealing cement is then applied to these channel cavities about eachsheathing panel unit, as illustrated and described in the copendingapplications to which reference has been made. If preferred, the plasticcement may be added to the channels of the stretchers, beforeapplication of the panel units, so that the entire vertically extendingcavity between units will be lled with such cement after completion ofthe assembly as indicated in Fig. 2.

What I claim is:

l. Building wall sheathing structure comprising a support membergenerally of channel form disposed with its channel cavity opening out-Wardly of the general plane of the wall, a metallic sheathing panelhaving a rectangular face part, with an inwardly turned lip part on oneedge extending into and along said channel cavity, said support memberhaving a laterally projecting longitudinally extending flangecooperative with the channel side part of said support member to providea shoulder recess, and an insulating board backing for said panel facepart having an edge part seating in said recess and there conned by saidpanel face part.

2. A building wall construction comprising a pair of parallel supportmembers of generally channel form disposed with their channel cavitiesopening outwardly of the general plane of the wall, laterally projectinglongitudinally extending flanges on said members cooperative with thechannel side parts of said members to form shoulder recesses, a memberdisposed transversely of said support members and carried at theopposite end portions thereof by said ilanges, said last mentionedmember being formed to provide a shoulder recess at the side thereof, asheathing panel carrying a projecting lip extending into the channels ofsaidsupport members and cooperating with the walls thereof for holdingsaid panel to said members, and an insulating board backing for saidpanel having edge portions seating in said shoulder recesses of all saidmembers and there conned by sai-d panel.

Y 3.

4. A building wall constructionl comprising a support member generallyof channel form disposed with its channel cavity opening outwardly ofthe general plane of the wall, a sheathing panel carrying a lipextending into said channel cavity out of contact with the wallsthereof, said support member having a laterally projectinglongitudinally extending ilange cooperative with the channel side partof said support member to provide a shoulder recess, and an insulatingboard backing for said panel face part having an edge part seating insaid recess and there conned by Said panel face part.
